Early Saturday morning, Elisashvili allegedly entered the courthouse in the capital Tbilisi by breaking a window with a hammer. He then allegedly poured gasoline and tried to set the building on fire, the Interior Ministry wrote on social media.
Elisashvili has been detained. He is said to have had a firearm and injured an officer during his arrest.
Georgian authorities have released video from the scene showing a gun, lighters, gasoline and broken glass. The AP news agency has not been able to verify the video.
The arrest comes a day after anti-regime protests took place in Tbilisi. The 47-year-old Elisashvili is one of the leaders of the opposition coalition Lelo. Several Georgian opposition leaders are accused of crimes and are in prison or living in exile. According to the opposition, the charges are politically motivated.
